Abstract: A method of bending a long member includes applying a tensile force to the long member to draw out the long member in a lengthwise direction thereof, measuring a displacement of the long member after commencement of the application of the initial tensile force, and bending the long member by applying a correction tensile force and a bending pressure for bending the long member into a curved shape in the lengthwise direction simultaneously to the long member upon the displacement exceeding a predetermined tensile fracture threshold value within a predetermined period of time or after a lapse of the predetermined period of time without the displacement exceeding the tensile fracture threshold value. The correction tensile force is smaller than the tensile force at the time the displacement exceeds the tensile fracture threshold value or the tensile force at the lapse of the predetermined period of time.

Abstract: The present invention provides a flame retardant polyester resin composition that is free from halogen and can have a high level of initial flame retardancy and maintain flammability even after a long-term heat aging test. By allowing an organophosphorous flame retardant (B) represented by the general formula (1) below: (where n=2 to 20) and a nitrogen compound (C) to be contained at a specific ratio with respect to a thermoplastic polyester resin (A), it is possible to obtain a flame retardant polyester resin composition that can have a high level of initial flame retardancy and maintain flammability even after a long-term heat aging test.

Abstract: The present invention is intended to provide a non-halogen flame-retardant polyester resin composition that has a high level of low warping properties and is capable of providing a molded product free from sticky residue in which the bleed-out of the flame retardant is suppressed even when the molded product is exposed to a high temperature environment. The flame-retardant polyester resin composition, having a high level of low warping properties and capable of providing a molded product free from sticky residue in which the bleed-out of the flame retardant is suppressed even when the molded product is exposed to a high temperature environment, can be obtained by incorporating an organic phosphorus-based flame retardant represented by the following general formula (1) and an amorphous resin at a specific ratio relative to a thermoplastic polyester resin. where n is an integer from 2 to 15.
